Presenting the Shubb Standard Electric Guitar Capo C4K Well made and still affordable, the polished nickel finish and a host of other features continueally make the Shubb Standard Capo a best seller. Not to be outdone, the series has been upgraded to include the patented roller ball closure, making this not only the most affordable high-end capo on the market today, but the one with the smoothest action. Durability, reliability and affordability define Shubb Standard Capos. Traditional Look Distinctive Design How It Works Shubb Capos work on an "over-center" locking principle. If you've used one, you know the feeling. As you close the capo onto the neck, it passes through a point of greatest resistance (the center), and then relaxes somewhat into its locked position. All Shubb Capos are designed to provide just the right amount of pressure applied in the closed position for the truest tone. Innovative Design It is a well-known fact that if a capo is too tight, it can stretch the strings out of tune. Most players understand that there is a "just right" amount of pressure for best capoing, too. It is this basic thought premise that led Shubb to their original innovative designs. Most designs incorporate a unique over-center locking mechanism that provides an unrivalled combination of power, speed, accuracy and ease of use. One smooth flip of the lever locks it securely in place, and removes it just as quickly. Best for Intonation And the Shubb capo is by far the best at eliminating the tuning problems that can occur when in use. Its soft, resilient rubber is specially designed to work just like a fingertip, so it doesn't bend the strings over the frets. Its closing action is just like your hand, so it doesn't pull the string off center. As a result, no re-tuning is necessary!
